About this plugin
Accept cards, bank payments (ACH), and stablecoins (USDC and USDT) on your WooCommerce store through a single checkout and a single platform.
SaturnShift for WooCommerce connects your store to your SaturnShift account in one click. There are no API keys to copy and no second system to reconcile. You choose which payment methods to offer, and they appear at your normal WooCommerce checkout.
Unlike a crypto-only gateway, SaturnShift brings cards, ACH and stablecoins together in one platform. Take a card, a bank payment, or a stablecoin on the same checkout, and manage all of it, refunds, reporting, settlements, invoices and payment links, in one place.
What your customers can pay with
- Credit and debit cards
- Bank payments (ACH)
- USDC and USDT stablecoins, accepted on Ethereum, Base, Polygon and Arbitrum
How it works
- Connect once, no keys. Click “Connect with SaturnShift”, approve, and the plugin pulls in the payment methods you have enabled, along with your branding and surcharge rules, and registers its webhook automatically. There are no API keys or secrets to copy.
- Same checkout. At “Place Order” the buyer completes payment on your hosted SaturnShift checkout, then returns to your order page.
- Orders stay in sync. Signed webhooks move each order between Pending, Paid, Failed, Expired and Refunded.
- On-chain receipt. Stablecoin orders show the settlement network and a block explorer link on the order, in “My Account”, and in order emails.
- Refunds. Refund card and stablecoin orders from WooCommerce or from your SaturnShift dashboard.
Everything else lives in SaturnShift
Reporting, invoices, settlements, payment links, analytics, customers, and native QuickBooks Online accounting sync all live in your SaturnShift dashboard. The plugin stays lightweight so your store stays fast.
Works with your checkout
Supports both the classic checkout and the WooCommerce Cart & Checkout blocks, and is compatible with High-Performance Order Storage.
Requirements
You need a SaturnShift account to use this plugin. You can create one for free during the connect step if you don’t have one yet. Orders are settled in USD; if your store currency is not supported, the plugin shows a notice and hides itself at checkout until you switch to a supported one.
External services
This plugin connects your store to SaturnShift, a third-party payment service, to
create checkouts, keep orders in sync, and process refunds. It cannot function
without this connection. The following describes what is sent and when.
io)
Used server-to-server for all payment operations.
- When a customer places an order, the plugin sends the order amount, currency,
order id and your store’s return URLs to create a hosted checkout.
- On connect, the plugin registers a webhook URL on your store and fetches your
merchant configuration (enabled payment methods, branding, surcharge rules).
- When you issue a refund, the plugin sends the order reference and refund amount.
- SaturnShift sends signed webhooks back to your store to update order status.
No customer payment card numbers or bank details pass through your WordPress site;
those are entered directly on SaturnShift’s hosted checkout.
